<p>A security device for forming a ring or shackle seal. The device includes a housing (14) at one end of a band (10) into which a male element (12) at the other end of the band is insertable. The housing has opposing laterally offset teeth (28) integrally formed therein for interlocking with complementary recesses (54, 56) in opposite faces of the male element to prevent withdrawal of the male element from the housing. The housing includes only the one entrance (16) for receiving the male element which element may include blocking means (60, 62) for occupying the opening into the housing. The device confers improved security in that the teeth are inaccessible for pre-tampering prior to the seal being formed and once formed, access into the housing is inhibited by the blocking means. <IMAGE> <IMAGE></p> |
